My presentation at the inaugural Edge of the Web conference in Perth, Western Australia on 6 November 2008. An introduction to Enterprise 2.0/Web 2.0 and then a look at business benefits plus a very quick look at a couple of case studies. It shares significant content with my earlier E2.0 talk, but is tighter and more focused. A full transcript is at http://www.acidlabs.org/2008/11/19/enterprise-20-a-new-age-of-aquarius/
